NOTES:
~~~~~
a. Times listed are minimum. This instruction interlocks the <ea> calculate
and execute stages and synchronizes some portions of the processor before
execution.

b. Times listed are typical. This instruction interlocks the <ea> calculate
and execute stages and synchronizes some portions of the processor before
execution.

c. This instruction interlocks the <ea> calculate and execute stages.

d. Successive in-line MOVE16 instructions each add 8 clocks to the <ea>
calculate and execute times

e. Typical measurement for three-level table search with no descriptor writes,
no entries cached, and four-clock memory access times.

f. This instruction also synchronizes some portions of the processor before
execution; times listed are minimum in this case.
